The improved ventilator herein illustrated and described is constituted as a frame of rectilinear configuration, spaced apart supporting elements assembled with said frame, supporting brackets adapted to be adjustably mounted upon said supporting elements, and louvers assembled with said supporting brackets.

The frame, as shown, is composed of sheet metal. It includes a top member I0, a bottom member H and side memberslzand [3. The top member Ill is constituted as a plate having downwardly extending, interior and exterior flanges, the bottom member H is constituted as a plate having an upwardlyextending interior flange and a downwardly extending exterior flange, and each of the side members [2 and I3 is constituted as a plate having an inwardly extending, interior flange and an outwardly extending, exterior flange. Meeting end portions of the top and bottom members Ill and H and the side members l2 and I 3 may be in overlapping relation.

The spaced apart supporting elements of the ventilator are constituted as vertically disposed metallic pipes or rods, each denoted 14, having their u per ends secured to the top member ill of the frame and their lower ends secured to the bottom member ll of said frame. Each pipe or rod" I4 is of uniform diameter throughout its entire length, and the upper and lower end portions of said pipes or rods are removably fitted to annular elements H) which are themselves secured,

as at Hi, to said top and bottom frame members. And, too, the pipes or rods M are of equal diameter.

The su porting brackets of said vent lator, each 7 indicated l1 and one disclosed in detail in Fig. 4

of the drawings, are each constituted as a collar I8, of size to be snugly slidable along the pipes or rods [4, and a louver sup orting member I9 integralor rigid with said collar and situated at the exterior side thereof. A set screw 2!] in each collar I8 is ada ted to be turned home against the p ne or rod u on which the collar is situated to fasten said collar in fixed relation to said pipe or rod and loo ened to permit the collar to be slid lon it d nally of the pipe or rod.

As disclosed in Figs. 1 to 4 of the drawings,

ment piece uponandextending upwardlyfrom the upper edge ofeach'upper ledge 22-is denoted 2d, a flange upon and extending exteriorly from the upper edge of each attachment piece 24 is indicated 25, and a second attachment piece upon and extending downwardly from the lower edge of each lower ledge 23 is represented 26;

As shown in Fig. 5, the louver supporting mem-- ber consists of a radially extending web 21 on the collar 18 and a single downwardly anclexteriorly extending ledge 28 on the web 21. Attachment pieces 29 and so on the ledge 28-" are equivalent to the attachment pieces 24 and 26, and a flange 3i! on theattachment piece a 2.9 is equivalent to the flange 25.

The louvers ofi the ventilator: desirably can be composed of metal, as-can also the supporting: brackets, and as shown said louvers are disposed:

in horizontal planes "andl'parallel relation;

As disclosed in Figs. 1 to 3, upper louvers 32 are supported upornupper'ledges 22L' 'of' horizontally alined supporting members I 9, lower louvers 33 are supported upon lower'ledges 23 of horizontally alined supporting'members I 9", and lower portions of theupper-louversa32areiin overlapped relation to upper. portions of the lower'louvers 33. A first attachment piece34 .uponand extendingupwardly from the upper edger-f each upper louver 32 issecured, as at 35, to and againstfirst attachment pieces 24." on upper ledges 22 of supporting brackets Hiwhich are inthe same horizontal plane, anda secondattachment piece 36* upon and extending downwardly from the lower edge of each lower: louver 33 is secured,

as at 31'; to andagainstsecond'attachment pieces 26 onlower ledges23 of "supporting brackets ll which are in the same horizontal plane. In the disclosure as made, lower portions oflower louvers 33are in overlying, exteriorly spaced relation to upper portions of adjacent upper louvers 32 just beneath, the upper portion of the uppermost up-- per louver 32 is situated below the body of the top frame member between its downwardly extending interior-and exterior flanges, and a lower portion of the lowermost louver 33 is at about the elevation of and disposed exteriorly of the bottom frame member ll,

As shown in Fig; 5; a single louver 38 is supported'upon the-single led'ge28, and in an installation includinglouvers as in said Fig. 5 lower portions of upper louvers 38 desirably will overlie and be in exteriorly spaced relations to upper portions of lower louvers-381 Attachment pieces 39-and 40 on single louvers such as 38 when employed will be secured to and against attachment pieces: such as 29 and 33- upon the members by which said single louvers are supported.

In the illustrated embodiment ofthe' invention, the louvers span-the distance between adjacent supporting brackets ll, adjacent horizontally alined'louvers meet at the midlengths of the ledges-22 and 23 of the central supporting brackets, and outerend portions of said louvers terminate in proximate relation to the side frame members !2 and I3. It will be apparent that each of the louvers could be constituted as a single length spanningthe distance between said 4. side frame members. Also it will be apparent that the ventilator can incorporate louvers of various different types and configurations.

The parts of the ventilator can be fabricated at a factory, shipped knocked down and assembled in the field.

In the accomplishment of installation of the ventilator, the top, bottom and side frame members will be fitted to an opening in a building and fastened in place in any suitable and convenient manner, as by screws, nails, screw bolts, etc. The supporting brackets l1 will be placed upon the supporting rods or pipes I l, and, after said supporting brackets are applied, said supporting rods or pipes: will be assembled with the frame and building in the manner as disclosed in the drawings. The means which fastens the annular elements I5to the top and bottom frame members In and l 1 also will enter the structure of the building; The louvers desirably will be assembled with the supporting brackets after these have been adjusted to preferred locations on the vertical rodsior pipes; Lower louvers 33 preferably willzbe-placed'in position before adjacent upper louvers 32 are applied.v
